Hydro assist will help. You'll need to get a different steering box with extra ports and a hydraulic cylinder. You can drill and tap the steering box yourself, if you're willing to take yours apart. Lots of info on 4x4 forums to sift through about box tapping, hydraulic cylinder stroke length, pump mods, hose routing, power steering reservoirs, etc. You can also probably get a kit from PSC, but it'll cost some money. A good power steering cooler is also a good idea, if you do any off-roading. I've had a steering pump so hot, it seized up, and water would steam off of it. It's amazing how much stress large tires put on everything.
